Game Douyin H5

Goal

Turn a vague "Douyin H5 Interactive" request into a concrete browser delivery shape before implementation starts.

Outputs

Follow the gsp-orchestrator output strategy:

• inline (default): present the route, shell rules, file structure, and adaptation constraints in conversation.
• minimal or full: write or update docs/game-studio/platform-implementation.md.

Use ../../shared/templates/douyin-h5-shell.md whenever a persisted shell decision record would help.

Use when

• the platform is explicitly Douyin H5 Interactive, 抖音互动作品, 抖音互动空间, or 抖音互动H5
• the deliverable must remain H5-only
• the work is portrait-first and mobile-first
• the user needs guidance on app shell, screen structure, canvas vs multi-screen route, or vertical adaptation before coding

Strong signals

• 做一个抖音互动作品
• 做一个抖音互动空间
• 做一个抖音互动H5
• 平台只接受H5，要竖屏适配
• 先定项目框架、文件结构和适配方式
• 先别写玩法，先把H5壳和结构定下来

Treat these as a signal to lock the platform shell before deeper implementation work.

Use

• ../../shared/reference/douyin-h5-interactive.md
• ../../shared/checklists/ui-ux-hard-rules.md
• ../../shared/reference/browser-2d-specialist.md

Lock these before coding

• primary route: screen-first interactive, canvas-playable interactive, or world/canvas plus DOM HUD
• portrait shell: viewport-fit=cover, one app-shell, safe-area ownership
• adaptation model: ratio shell only or design-space plus viewport mapping
• minimum state surface: loading, menu, primary interactive state, result
• ownership boundaries: shell, screen state, gameplay state, adaptation math, HUD/overlay
• interaction budget: one-hand play, thumb zones, first-action clarity

Route choice

• screen-first interactive for quiz, branching, reveal flow, or text-heavy participation.
• canvas-playable interactive for aiming, timing, physics, spatial play, or a continuous loop.
• world/canvas plus DOM HUD for spatial play that still needs menus, HUD, result packaging, or overlays in DOM.

If the request still mixes multiple routes, do not silently improvise a hybrid. Lock one route first. If the route still cannot be locked from the prompt, ask a clarifying question or route upward to gsp-requirements-brainstorm.

Lock the portrait shell first

• Require viewport-fit=cover and portrait-first layout assumptions.
• Use a single app-shell that owns the visual ratio, safe-area padding, and overflow behavior.
• Use a fixed design ratio or fixed design-space before tuning details.
• Treat the screen shell and the interactive core as separate layers.
• Keep critical actions in comfortable portrait thumb zones unless the concept explicitly demands otherwise.

File shape

• shared root: index.html, css/styles.css, assets/ or images/
• screen-first: js/app.js, js/ui/, js/data/, js/config/
• canvas-playable: js/main.js, js/core/, js/game/, js/ui/, js/input/, js/audio/, js/config.js
• world/canvas plus DOM HUD: js/game.js or js/main.js, plus js/core/ or js/rules/; use lib/ only for true shared runtime code

For the exact shell record, fill ../../shared/templates/douyin-h5-shell.md.

Important adaptation rules

• choose ratio shell only or design-space plus viewport mapping
• if canvas is involved, remap input into design-space before gameplay reads it
• keep HUD and overlays outside the playfield when text density or safe-area handling matters
• lock the result state early so it does not become a bolted-on screen

Do not do these

• Do not start from a desktop layout and shrink it into portrait later.
• Do not leave route choice implicit when the request could mean either multi-screen interaction or real-time gameplay.
• Do not mix DOM state, gameplay state, and adaptation math in one oversized file.
• Do not treat safe-area padding as the full mobile adaptation problem.
• Do not overload the top and bottom bands with permanent UI just because portrait space feels available.

Boundary with other skills

• Use this skill to lock the platform-specific H5 shape.
• Use gsp-ux-flow-designer to shape onboarding, menus, CTA hierarchy, and first-minute comprehension.
• Use gsp-web-2d-specialist after the browser route is chosen and the project needs concrete 2D implementation guidance.
• Use gsp-feedback-design after the shell and route are explicit.
